The small population size makes this species very vulnerable, particularly to grazing by goats, collectors and possibly landslides. Its low genetic diversity may also limit the species' capacity to adapt to changing environmental conditions. Potential tourist development would also lead to road construction that will favour the dispersal of invasive alien species, especially Centranthus ruber which could hybridize with C. amazonum.

Actions in PlaceThis species is under cultivation in the Brest National Botanical Garden, and seeds have been sent to the National Botanic Garden at Porquerolles. No legal or in situ measures have yet been taken since this species was described in 1998.
